I believe the point is that those in history and the future who have died , physically, for whatever reason, before the time of the rapture will be reunited with the glorified version or elements of their physical body... Though maybe scattered like dust... The elements are still around to be gathered... Perhaps our glorified bodies are simply our current bodies without deformities, ware and current limits... Such as time... Whenever it happens... Don't worry if you survive till then... You will still experience it.
